摘要：

We describe an instrument that extends the state of the art in a single-molecule tracking technology, allowing extended observations of single fluorophores and fluorescently labeled proteins as they undergo directed and diffusive transport in three dimensions. We demonstrate three-dimensional tracking of individual quantum dots undergoing diffusion for durations of over a second at velocities comparable to those of intracellular signaling processes.
